It's arguably one of the most anticipated singles of the year, but is Lady Gaga's "Born This Way" all that new?

After leaking the lyrics on her Twitter account, Gaga debuted the single, from her album due out May 23, on Friday. And while #bornthiswayfriday remained a trending topic on Twitter all morning – another term began trending as well: "Express Yourself," as in Madonna's 1989 Top 10 hit. By late morning, "Express Yourself" had become more popular than #bornthiswayfriday on Twitter, with fans and foes alike comparing the songs.
